Hypertension or High blood pressure is a prevalent cardiovascular disease in the United States and other nations around the world. It is estimated that 1 billion is affected with the disease and about 7.1 million hypertension related mortalities annually. It is a condition in which the long-term force of blood against artery walls is high enough to ultimately cause heart attack, aneurysm, stroke or left ventricular hypertrophy leading to congestive heart failure. Many people with hypertension do not realize they have because the symptoms are subtle and that it generally develops over a long period of time. Most often, vital organs like the kidneys and eyes may damage or other diseases may occur before it is detected; for this reason, it is often called the "silent killer (American Heart Association, 2014). According to Woo & Wynne (2012), a report from the World Health Organization indicates that suboptimal blood pressure higher than 115mm Hg (systolic) is liable for 62% of all cardiovascular disease and 49% of all ischemic heart disease. A normal blood pressure level is systolic reading of blood pressure (SBP) less than 120mmHg with diastolic level (DBP) less than 80mmHg. Hypertension disease has the following stages. A pre-hypertensive level is SBP 120-139, and DBP 80-89. Hypertension stage 1 is SBP 140-159, with DBP of 90-99. Hypertension stage 2 is SBP greater than or equal to 160 with DBP of 100 or more. Stress and emotional tension may temporarily increase blood pressure; but it would not be considered as hypertension unless it remains that way after the situation dissolves or improves (Woo & Wynne, 2012).
Epidemiology studies depict that up to about 60% of the condition is inherited but environmental factors can also play a large role in it (Nadar, & Lip, 2011). In the United States, African Americans make up 12.8% of the population, but their...

Health Promotion Among Diverse Populations

...Health Promotion Among African Americans Family-Centered Health Promotion 02/22/2015 African Americans or Blacks have been a part of our countries history for very long time now. They have been, up until the recent years, treated unequally and discriminated. Unfortunately discrimination against African Americans and Blacks are still prevalent today. Their past in our country is not something we should ignore; rather use it as a tool of understanding the African American culture. Their perception of healthcare and their willingness to seek help could be linked to the fear of social discrimination and the possibility of being treated differently if the healthcare providers are predominately white. The health disparities among African Americans today is something that cannot be ignored and is something that healthcare professionals need to take seriously. This paper will talk about the health disparities among African Americans and how we can make change to this by approaching the problem with health promotion and prevention techniques. According to the Centers for Disease Control and Prevention, 2015, the population of African Americans is estimated to be a 45 million; which is 15.2 percent of the United States population. Around 14.7 percent of the African American populations are shown statistically to live in fair or poor health. This particular race is known to suffer from high incidences of Heart Disease, hypertension, diabetes, obesity, poverty and high......

...Hypertension Hypertension is high blood pressure. Blood pressure is the force of blood pushing against the walls of arteries as it flows through them. Description As blood flows through arteries it pushes against the inside of the artery walls. The more pressure the blood exerts on the artery walls, the higher the blood pressure will be. The size of small arteries also affects the blood pressure. When the muscular walls of arteries are relaxed, or dilated, the pressure of the blood flowing through them is lower than when the artery walls narrow, or constrict. Blood pressure is highest when the heart beats to pump blood out into the arteries. Between beats, when the heart relaxes to refill with blood, the pressure drops to its lowest point. The blood pressure peak, when the heart pumps, is called systolic pressure. The blood pressure trough, when the heart is filling, is called diastolic pressure. When blood pressure is measured, the systolic pressure is stated first and the diastolic pressure second. Blood pressure is measured in millimeters of mercury (mm Hg). For example, if a person's systolic pressure is 120 and diastolic pressure is 80, it is written as 120/80 mm Hg. The American Heart Association considers systolic blood pressure less than 140 and diastolic blood pressure less than 90 normal for adults. Hypertension is a significant public health problem. Since it has no symptoms, many people are unaware that they have hypertension. In the United......

Health Disparity

...INTRODUCTION African Americans including those of more than one race constitute 15.2% of the U.S population. (CDC, 2011) The National Health Interview Survey (NHIS) conducted in 2012 reports that white (38%) and Asians (37%) are more likely to be in excellent health than African Americans (31%). (NHIS) 14.6% of blacks of all ages reported of poor or fair health which is higher than the general population.37.9% of African American men and 57.6% of women above the age of 20 are obese.39.9% of men and 44.5% of women above 20 of African American origin have hypertension.17.8% of African American people under 65 does not have health insurance.(CDC,2011) Leading causes of death among African Americans are heart disease, cancer and stroke. Obesity and diabetes are twice as prevalent among Africans compared to white adults. They have the largest death rates from homicides compared to any racial or ethnic population.(CDC,2011) African Americans also have the highest incidence and death rates from colorectal cancer and HIV infection rates. Prescribed HIV treatment among African Americans living with HIV is also less compared to white adults.(CDC,2011) A larger percent of African American adults live in poverty and does not have a high school education compared to the general population. All of this data points toward poor health status among African Americans. Studies have shown that African Americans underutilize......

Patho Case Study 2

...1. What risk factors for primary hypertension are evident from K.H.’s history and physical data? K.H. is a 67 year old African American male, his ethnicity and age are non-modifiable risk factors, which means it is circumstances that he cannot change. Unfortunately African Americans are more susceptible to hypertension and after 55 years old there is a 90% chance that Americans regardless of ethnicity will develop hypertension. According to a PowerPoint from Dr. Marian, HSC 3211 on Hypertension, the ethnicities most likely to have hypertension are as follows: African American > Puerto Rican > Hispanic American > Caucasian > Cuban American. K.H. is also overweight by 30 pounds. Obesity is a leading cause of hypertension because excess weight makes it more difficult for the heart to pump blood throughout the body as efficiently as it would if K.H. was not overweight. He has already started lifestyle modifications such as a salt-restricted diet in hopes of lowering his blood pressure. Sodium causes the muscles around blood vessels to becomes stronger and thicker as a result of trying to ease the extra burden the arteries are experiencing. However, this is not a good thing because it causes the arteries to become more narrow thus raising one’s blood pressure even higher. With this evidence, it is important that K.H. stay on his salt-restricted diet if he hopes to lower his blood pressure and avoid other organ damage from excess salt. K.H. has high blood pressure at......

Closing the Gap in Health Disparities of African Americans

...Gap in Health Disparities of African Americans Rosie Vasser Grand Canyon University Closing the Gap in Health Disparities of African Americans Historically speaking African Americans have had harder access to healthcare due to a number of socioeconomic reasons. Many are unable to even get to a facility. When thinking about poverty in America one must associate African Americans with poorer health, less access to medical care and higher risk factors than others. Stressors alone within this group places them at higher risk for hypertension, smoking, diabetes, etc. Lower income limits the availability to healthier food and quality healthcare. AA persistent struggle to achieve the American dreams translates to their persistent struggles with health. The dominate society generational connection to wealth, affords them the ability to access the best in healthcare. AA has very limited access to quality healthcare. According to Eileen M. Crimmins, Mark D. Hayward, and Teresa E. Seeman (2004), “People who are poorer and who have less education are more likely to suffer from diseases, to experience loss of functioning, to be cognitively and physically impaired, and to experience higher mortality rates” (2004), This essay will compare and contrast the health status of the African American minority group and compare to the national average. We will discuss the current health status of this minority group, how health promotion is defined by African Americans, and what health......

Heritage Assessment

...three cultures and evaluate how families subscribe to these traditions and practices. Cultural competency involves more than just asking questions, but it opens up the diversity of the patient’s culture. Nurses must become aware of their own cultural biases and focus on the cultural beliefs and values of the patient by performing a heritage assessment (Edelman & Greiner, 2010). This heritage assessment will give the nurse a clearer picture of the patient’s background and in the process will improve the quality of care and patient outcome (Schimdt & Owens, 2012). I had an opportunity to perform a heritage assessment on three people from three different cultures. The three cultures that I performed a heritage assessment included: an African American, an Asian person (Vietnamese) and a Hispanic person from El Salvador. The Vietnamese person told me that she was born in the United States but her mother...

The Prevalence of Heart Disease for African Americans

...The Prevalence of Heart Disease for African Americans Lucinda Kroll Grand Canyon University The Prevalence of Heart Disease for African Americans American physicians have drastically reduced cardiovascular mortality and the death rates have decreased 17% since the 1990's (Nash, 2003). Their have been so many advances in open heart surgery, heart transplantations, and thrombolysis in the past decade. Their have also been great strides made in medications with heart disease patients (Nash, 2003). Unfortunately, the African American culture has not seen as much advancement as other cultures (Nash, 2003). African Americans have the highest rate of heart disease compared to all other ethnic groups (Nash, 2003). The CDC reports the 24.5% of deaths caused by heart disease in 2008 were African American and they had the highest percentage compared to other cultures (CDC, 2015). African Americans are at three time's greater risk to develop heart disease than Caucasians and two times more at risk of death from heart disease (Winham and Jones, 2011). For example, African Americans have been diagnosed at younger ages than Caucasians and are more likely to die from heart failure (Nash, 2003). They are also at a younger age when they experience their first myocardial infarction than Caucasians (Nash, 2003). Sadly stage 3 hypertension (ie., blood pressure >180/110), is reported to be the highest in the world for the African American community (Nash, 2003). This......

...Heritage Assessment Health Tradition and Cultural Comparison Sharon Nodine Grand Canyon University: NRS-429V March 20, 2016 “A growing realization that the United States is not a ‘melting pot’ in which immigrants assimilate into the mainstream culture, but a country of many cultures has led to a growing appreciation of different ethno-cultural groups” (EuroMed Info, n.d.). The Heritage Tool and it’s five competencies is designed to provide a framework for nurses to gain insight of the cultural practices of patients in order to provide culturally competent care that will result in better health outcomes (American Association of Colleges of Nursing, 2008). The Hispanic-American Assessment “Latinos comprise nearly 16 percent of the U.S. population, and this proportion is anticipated to increase to 30 percent by 2050” (Juckett, 2013). He continues to say, barriers to care have resulted in striking disparities in quality of health care for these patients. These barriers include language, lack of insurance, different cultural beliefs, and in some cases, illegal immigration status, mistrust, and illiteracy. The National Standards for Culturally and Linguistically Appropriate Services address these concerns with recommendations for culturally competent care, language services, and organizational support. Latinos have disproportionately higher rates...

...considered obese (CDC info at Obesity is one of the most discussed current health issue, because it is a precursor to hypertension, heart disease, type 2 diabetes, gall stone, breathing problems and certain cancers. Preventing over weight and obesity will in effect reduce or eliminate these conditions from the population. Obesity is the second leading cause of preventable death in United States. Obesity affects 97 million Americans that are over 30% of the population. It cost about $100 billion a year to manage obesity related disease. (NIH publication 98-4083). Overweight and obesity is very common in minority groups, but affects people of all ages, but the number rises with age, and has a particular relationship to socio-economic status. The lower the socio-economic status the greater the prevalence of overweight and obesity. Rational: We chose this health indicator because as nursing students, we think it is important to live a healthy lifestyle and also educate the public about healthy eating to prevent overweight and obesity. We believe obesity is a preventable disease. Too much time is spent by Americans sitting in a couch and watching television and playing video games than in the gym. Objectives: Since overweight and obesity is a “lifestyle” health issue, it is preventable. Obesity among Africa American is higher in relation to the general population. Genetic and environment factors play a major role in overweight and obesity.......

Teaching on Hypertensio

...When we spoke to the members of the stein center we were able to discover that many of them were eager to learn about hypertension, the reasons for their medications, and effects. They were very interested and just needed some clarification on the subject. There is a knowledge deficit in the community related to hypertension as evidence of personal communication. They voiced that their knowledge on the subject was very limited and needed more understanding. So by the end of the presentation that was given regarding hypertension they will be able to demonstrate understanding of what hypertension is and how to prevent or manage hypertension. We will measure the success of the education by handing the members pre and post exams as well as verbal surveys. The style of teaching will be visual, as well as audio. The members voiced that they learned best when there are visuals. They expressed that too much talking can bore them but if they are engaged there is a greater chance that they will grasp the concept. On June 19th 2012 at 11:25 am, my colleagues and I conducted a fifteen minute presentation on high blood pressure management for the members at the Senior Stein Center. Sixteen members participated in the teaching session, the member’s age range from 60 and up, male and female both participated, the race and ethnicities consisted of African American, Caucasian, Hispanic, and Asian. To determine the learning needs of that particular group, we provided a pretest prior to the......

The objectives of heart disease will be discussed and explored according to health data sources. Also, the impact of the effectiveness of the interventional programs that are designed and implemented to treat and prevent heart disease will be evaluated and discussed, as well. WHAT IS EPIDEMIOLOGY? In layman’s terms, epidemiology can be defined as the study of anything that happens or befalls men. According to Stanhope & Lancaster (2010), “epidemiology is the science that explains the strength of association between exposures and health effects in human populations.” This study deals with distribution and determinants of health related states and the purpose of these studies are to control health. The goal of epidemiology is to identify and understand the casual factors and mechanism of disease, disability, and injuries so that effective programs and interventions can be designed to prevent the occurrences of these disease processes......

Cardiovascular Disease in African American Women

...CARDIOVASCULAR DISEASE IN AFRICAN AMERICAN WOMEN Richard Allen Williams, M.D. Clinical Professor of Medicine, UCLA School of Medicine President/CEO, Minority Health Institute, Los Angeles, California Introduction Cardiovascular disease (CVD) has long been considered a disorder which principally affects men in our society; consideration of the occurrence of heart attacks in females, for example, has been largely an afterthought. In the past few years, however, it has become increasingly obvious that this is not a problem limited to males, but that it occurs with great frequency in women. We now know that CVD is the cause of death more than any condition in women over the age of 50, including cancer (1) and in fact is responsible for more than a third of all deaths in women (2). It is estimated that 370,000 women in the United States die from heart disease each year. However, our knowledge base regarding CVD in African American (AA) women has not kept pace with the accumulation of data on white females. Thus, there is a deficit of information about this subgroup and the prevalence of CVD despite the fact that black women have more risk factors for CVD than do white women (3). The purpose of this paper is to review the subject of CVD in African American women and to focus upon four principal CVD categories: Coronary artery disease (CAD), hypertension, stroke, and congestive heart failure (CHF).The impact of gender and race on each of......

...Hypertension is a major risk factor for cardiovascular diseases and stroke which have a systolic and a diastolic blood pressure level of >140/90 mmHg. 31% of US adults continue to suffer from hypertension, with minorities being more likely to have the condition. Of these, 25% have uncontrolled blood pressure. Data from the National Health and Nutrition Examination Survey (NHANES) for 1999–2002 showed that the hypertension prevalence rate was highest among African American, almost 50% higher than white people. African Americans develop hypertension at an early age, reach advanced levels of hypertension, are prone to experience further complications, and are less likely to attain control of their hypertension. Hypertension is a leading cause of preventable death in the United States and among African Americans. African Americans have the highest risk for hypertension-related deaths. Among all racial/ethnic groups, African American women have the highest prevalence (45%) and lowest control of high blood pressure (59%). NHANES data examining the 2001–2010 time period also showed African Americans were more likely to have uncontrolled hypertension than white people and Hispanic people. Poor adherence to medication has been identified as a major contributor to uncontrolled hypertension among African American patients. Women are about as likely as men to develop high blood pressure during their lifetimes. However, for people younger than 45 years old, the condition affects more......

...Keisha Jackson Professor: Steve Klense Introduction to Health Services Management The Johns Hopkins Hospital The Johns Hopkins hospital was founded in 1889 and four years later the Johns Hopkins University School of medicine was opened. They had an up graded medical school curriculum with emphasis on the scientific method, which included the incorporation of bedside teaching and laboratory research as part of the instruction and integration of the school of medicine with the hospital through joint appointments. Hopkins medicine is the first major medical school in the United States to admit women; the first to use rubber gloves during surgery; the first to develop renal dialysis and CPR. Two of the most far-reaching advances in medicine during the last 25 years were made at Johns Hopkins. The Noble Prize – winning discovery of restriction enzymes gave birth to the genetic engineering industry and the discovery of the brain’s natural opiates has triggered an explosion of interest in neurotransmitter pathways and functions. Johns Hopkins are also known for the identification of the three types of polio virus and the first “blue baby” operation, which opened the way to modern heart surgery. They are also the first to conduct many medical specialties, including neurosurgery, urology, endocrinology, and pediatrics. The mission of Johns Hopkins Medicine is to improve the health of the community and the world by setting the standard of excellence in medical education,...
